Application filed January 27, 1905. Serial No. 242,969.

To all Hill/071D it "may concern:

Be it known that we, JAMES C. KIMsEY and HENRY R. HEYL, citizens of the United States, residing at Philadelphia, Pennsylvania, have invented certain Improvements in Processes of Manufacturing Paper Bottles, Cups, or other Containers, of which the following is a specification.

The object of our invention is to cheaply and accurately manufacture cups, bottles, and other containers entirely of paper. This object we attain in the following manner, reference being had, to the accompanying drawings, in which Figure 1 is a vertical sectional view of a cup with a tapered body and illustrating our invention. Fig. 2 is a vertical sectional view of a container of an even diameter throughout and illustrating our invention. Figs. 3 to S, inclusive, are diagram views illustrating our improved method.

In manufacturing paper bottles, cups, or other containers for the purpose for which our nvention is intended they must be cheaply and accurately made, so that they will hold liquid or other material, and yet be so cheap that the cup or bottle can be discarded when emptied.

A is the body portion.

B is the bottom, and D is the locking-disk by which the bottom is held firmly to the body.

The body may be either tapered, as shown in Fig. 1, or may be made of an even diameter throughout, as shown in Fig. 2, according to the use for which the article is intended. WVe preferably make the containers with a slight taper, as shown in Fig. 1, so that they can be nested in packing and shipping, and when desired a closure E may be used, as shown in Fig. 1.

In carrying out the process we preferably coil a sheet of paper upon a suitable mandrel and cement the several coils together by paste or other cementing material. By this method we form what we term a seamless tube. The tube we preferably make in the form of a cylinder, as the cup or bottle is more readily manufactured in the cylindrical form than in any other shape, although we do not limit our invention to the particular shape of the body portion.

Referring to Figs. 3 to 8, inclusive, we will describe our improved process of making the down upon.

cup orbottle. The diagrams illustrate the several steps in connection with making the cup with tapered sides, as shown in Fig. 1. F is a cylindrical anvil having a flangef, the outer wall of which is slightly tapered to fit the taper of the body portion A, while the inner facef of the flange is at an abrupt angle, so as to form a surface against which the flange a of the body portion can be turned G is a wheel which when the body portion A is applied to the anvil breaks down the flange a over the edge of the flange of the anvil, as shown in Fig. 3; but the flange may be turned down by hand, if desired. The next step in the process is to force the flange a down against the inner surface f of the flange F. This is done, preferably, by means of a plunger II, having a beveled end It, as shown clearly in F l. W'hen the flange is turned down to the position shown in Fig. 4-, the plunger .IIis withdrawn and the flanged body is removed from the anvil. The next step in the process is to mount the bottom B on a plunger 1, with the flange b uppermost. The flanged body portion is then slipped over the bottom and the plunger, as illustrated in Fig. 5, until it assumes the position shown in said figure. Then it is desired to apply paste or other cementing material to the assembled parts, it is applied to the bottom B, as shown in Figs. 5 and 6, preferably by a brush K, having bristles k, which is inserted in the space, as shown in Fig. 5, and by depressing the brush the bristles will be forced under the flange a and against the inner surface of the flange b, applying the paste not only to the flange, but also to a portion of the surface of the bottom B. The brush may be made of any form desired and is preferably rotated as well as moved longitudinally. When the brush is removed after applying the paste, the flange b of the bottom B is forced into the annular cavity until its end preferably comes in contact with the bottom of the cavity, as shown in Fig. 7. Then the locking-disk D is forced into the space formed by the flange a, and this locking-disk is of such a size that it must beforced in place under pressure, so that it will in turn force the flange a, into direct contact with the flange b of the bottom B at a point near the bottom, and this disk forms a lock for securing the bottom to the body portion, and when the paste is applied, as

previously described, the flange a adheres to the flange b, while the locking-disk adheres to the bottom B.

In turning down the flange a of the body portion it is crimped to a certain extent; but this crimping tends to give a tighter hold of the flange upon the locking-disk when it is forced in position, so that in some instances cement is not necessary to make the joint waterproof or air-tight for the time being.

After the parts have been assembled they are preferably waterproofed, and this is usually accomplished by dipping the article in hot paraflin and allowing it to drip so as to produce a thin coating over the entire surface and making the joints absolutely air and water tight.

When the bottle or other container is to be closed, a cap E may be used, as shown in Fig. 1, havin a flange e, which snugly flts the mouth of the bottle or cup, and this cap is preferably provided with one or more tabs 6, so that it can be readily removedwhen desired.

WVe claim as our invention 1. The process herein described of manu facturing paper receptacles, said process consisting in making a tube, turning a flange on one end of the tube to form a straight annular cavity, forcing a flanged bottom into the tube from the opposite end to that flanged, so that the flange of the bottom will rest in the straight annular cavity, and forcing a locking-block into the flanged end of the tube under pressure whereby the flange of the tube is held to the flange of the bottom by the locking-block, substantially as described.

2. The process herein described of making tubular receptacles, said process consisting in making a paper tube, flanging one end of said tube to form a straight annular cavity, forcing a flanged bottom partly into the tube from theopposite end to that flanged, placing cement in the corner of the flanged bottom and forcing the flanged bottom farther into the tube so that the flange of the bottom will fit snugly in the straight annular cavity of the tube, forcing a locking-disk into the flanged end of the receptacle so as to press the flange of the body portion of the cylinder against the flange of the bottom at a point near the bottom, the cement fastening the flange of the body portionto the flange of the bottom, and the locking-disk to the bottom, substantially as described.

3. The process herein described of making tubular receptacles, said process consisting in making a paper tube, flanging one end of said tube to form a straight annular cavity, forcing a flanged bottom, with cement applied to the corner of said flanged bottom, into the tube so that the flange of the bottom will fit snugly in the straight annular cavity of the tube, forcing a locking-disk into the flanged end of the receptacle so as to press the flange of the body portion of the tube against the flange of the bottom at a point near the bottom, the cement fastening the flange of the body portion to the flange of the bottom, and the locking-disk to the bottom, substantially as described.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
